I have an IIS 7.5 server which, in order to access via Remote Desktop, I have to connect to Cisco VPN
It has several with several sites on it e.g.
site1 bindings: www.domain1.com, domain1.com site2 bindings: www.domain2.com, domain2.com site3 bindings: sub1.domain2.com, sub2.domain2.com
I have a multi domain, wildcard SSL certificate which works for *.domain1.com and *.domain2.com which I have 'friendly named' to * and set up the ssl bindings using appcmd (see here - ihave tried both * and explicit IP address)
The https versions of the site can be accessed when I am connected to the VPN, but when I access the sites from any computer that is not connected to the VPN, the https sites time out.
I had thought this was that there was maybe a firewall on 443, but I have checked with the ISP and am told this is not the case (although I would like to check this - whats the best way to confirm?)
When connected to the VPN, pinging the site gives 192.168.100.20, which is the network adapter, when it's not connected it's 85.blah.blah.blah. The IIS logs record all traffic as coming in on 192.168.100.20
Any ideas on checking the firewall, or on what else it could be?
